This is functionality that has existed for a looooong time on Windows (though not baked into the OS, typically as a $10 app or free with certain peripherals like Logitech mice).

While I like that it's free and supported as part of the OS... it's really hard for me to get too excited that has been available for 5? 10? 15? years on Windows. Especially to say "it just works!" This has been a solved problem for quite some time. I think the only interesting thing here is that it happens automatically by putting the devices near each other.
